BUCKLE.

SPECIFICATION formingpart of Letters Patent No. 726,312, dated April 28, 1903.-

Application filed January 25. 1902- Serial No. 91,229. (No model.)

To all whom it may concern:

Be it known that LAUGUST W.KRUEMLING,

a citizen of the United States, and a resident.

of Anderson, in the county of Madison and State of Indiana, have made a certain new and useful Invention in Buckles; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a perspective View of my buckle. Fig. 2 is a longitudinal section of the same. Fig. 3 is a plan view of the rear end portion of the buckle. Fig. 4 is a longitudinal section of the buckle and showing the strap.

The invention relates to buckles, especially for traces or straps; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings the letter a, designates the buckle-frame, which is of ordinary character, usually comprising the side bars I) b, the rear pivot-bar c, connected to downward extensions of one end portion of said side bars, and the front framebar d,

. cated at the opposite ends of said side bars bar d,which is at a higher level than the bar 0.

The tongue ecomprises the pivotal portion or eye g, the depressed shank 72, extending parallel to the general direction of the side bars, but at a lower level, the holding, portion h at right angles to the shank, and the terminal olfsetf at the end of said holding portion and parallel with said depressed shank.

The buckle is attached by means of its pivotal bar. The trace or strap is-readily connected by passing it through the frame, the terminal offset of the tongue being at the same time inserted through the proper perforation of the traceor strap in such a manner as to clear the same, the perforation then engaging the rectangular holding portion h of the pivotal bar and under the front framebar (1, so that its direction is parallel with the general direction of the side bars and at right angles to that of the holding portion h of the tongue. squarely against the wall of the perforation with which the holding portion engages, and the buckle-frame is locked on the strap by means of the terminal offset of the bearing portion.

In this improvement it is designed to provide fora distribution of the strain over the length of the buckle-frame in a direct manner in such wise as to avoid a breaking strain. The strain is a square pull on the holding portion of the tongue, which is supported by the pivot-bar engaging the eye and the front frame-bar engaging the upper end of the holding portion 7t at its junction with the terminal offset, this engagement in the angle 1*, formed by said offset and holding portion, being allowed for by the play of the eye of the tongue on the pivotal bar. This play is provided for by making the pivotal bearing of the pivotbar somewhat smaller than the elongated or elliptical eye of the buckle-tongue, the major axis of this eye having a parallel relation to the depressed shank of the tongue. In the construction shown the bearing 7.; is reduced,

the pivot-bar being larger on each side of it, so as to prevent the eye from having such lateral movement as to throw it out of position.

The strain on the strap is therefore side bars and at a lower level than the front top of said frame-bar and parallel with said frame-bar, and having an elongated or ellipdepressed shank, substantially as specified. IO tical eye with its major axis about parallel In testimony whereof I affix my signature with said shank, the holding portion of said in presence of two witnesses.

tongue at right angles to said shank and AUGUST W. KRUEMLING. adapted to engage the inner margin of said \Vitnesses:
